Well, the attempt to convert my 66 Biscayne from grocery getter 283/PG to a BBC NHRA S/SS class pretender, has suffered a set back.  I was trying to complete this project on the cheap so when the opportunity to purchase a newly rebuilt 454 with several upgrades, 10.9 to 1 compression, single plane intake and demon carb, for half the market value, I jumped on it.  That motor along with a rebuilt turbo 400, Be Cool aluminum rad, super sport 12 bolt, 4 link all new differential w/posi & 4:10 gear set made up the heart of my build.  With Hooker long tube headers and a killer custom 3" dual exhaust pipes turned down in front of the differential.  I was ready to make a couple test hits.

Prior to making that trip to the strip, I decided to put a few miles on the build in the local country side.  That resulted in the 454 losing power within a couple miles and I then shut it down.  Put it in the trailer and headed back to the shop.  The 454 did not come with any warranty other than hearing it run prior to installing it in my car.

Motor had a Crane Cam that was totally wiped out.  Metal shavings in the oil and it seems a couple of the valve seals had mushroomed.  Valve train was full roller, tall system.

I could have the block flushed, new bearings, cam and rebuild the valve train but I could also buy a complete crate BBC ready to run or a long block to bolt on my intake, carb and headers.  My confusion is over what motor will bring maximun value to the car.  I do intent to sell it within 12-24 months after it is running.  My budget is under $8,000 which rules out an LS with so many parts required along with the motor.  I want to run 93 octane and have it streetable.  I have listed the various options and I would give preference to the blocks that will accept the components I have from the 454.

427 is nostalgic but probably the least performance

454 is so easy, good performance but not period correct for 1966

496  No clue??

502   "   "

540   "   "

572  Probably too much power

You can`t argue with Large Engine Displacement.

I currently have a 427, and a 502....Sold my 454.

It`s all about the engine builder, the quality of the parts and the parts that work well with one another.

With the Right Builder with 8K budget you can build a Great Strong 427, 454 and 496.

If you want to sustain the vintage appearance the 427, 454, 496 are the routes to go.  Friend of mine just bought a Blueprint GM 496 from Summit for his 67 SS Chevelle.  Looking in the engine compartment you would never know he now has 100 cubic inches more than the original.  He opted for the milder 480 hp version for his.  It even has a 30 month 50,000 mile warranty!  https://www.summitracing.com/parts/mll-bp4963ctc

I voted for the 454, meaning for you to fix the engine you have. I'm an Oldsmobile guy and I buy stalled project Olds engines for cheap but I go through them measuring/checking everything. You never know what's inside till you open them, sometimes it's fine but sometime it's a can of worms. I always run them on a test stand also because even though I have a 2-post lift and all the gizmos to make installation a one man job, they still don't just jump in. At 68 I'm still doing what I did at 16 but no more pipe tripod and chain fall working outside under a tree in the summer and under a tarp in the winter. Here's an example of a 461 Olds engine I bought for less than the machine work would cost. It wouldn't last long but luckily it was never run. Engine has ARP Studs but the front main studs were "buried", one half way, other down a couple of threads. If you don't open them you'll never see the "worms" till it's to late.

Well it came down to a bargain buy with good street manners and good E.T. potential.  A new 468, quality build with some shelf life.  Edlebrock aluminum heads and matching cam.  I could not resist it with the aluminum low profile intake and dual 4 bbl carbs.

I have always been the guy with something different and I enjoy that.  The original build was a single plane 4 bbl carb and estimated to be 540 hp.  After swapping over the MSD, Hooker long tube headers, extra capacity moroso pan etc, it will be installed and eventually make a trip for dyno tuning.

Please wish me luck, I have too much invested in this car to lose another motor.

Norman,

Really hope that works out for you. That longer stroke motor should be very torquey (is that a word?), good for a heavier car. What compression does it have and is the cam a roller or flat tappet? If it is a flat tappet cam be sure to use oil that has zinc in it like the Joe Gibbs Driven oils.

Keep us posted!

Thanks for the tip.  One reason I decided to go with more torque was most of the local tracks are running 1/8 mile.  The more common single plane, single 4 bbl won't have time to work as well in an 1/8 mile.

Compression is 9.75 to 1 and cam is flat tappet.  I really wanted to run 93 octane gas also. 

Looking forward to hearing the thunder.
